    Good progress. Interested to see the cause of the triangle wave.

    I agree with “Ride” Shouldn’t that signal be a nice clean sine wave otherwise won’t we get spatter all over the band especially when we return to full power?

    Well, you may not be able to bless the operation of the PA stages quite yet...you might drive the PA's with a 10 dBM signal from your signal generator and see if you get full output.

      Thought about doing that, but I think I know what's wrong, if that does not work I'll be back to inject a signal

    for all those dude that had to fix that driver ic on the RF pcb
    sorry about that it was a booboo
    we thought the ic could do more than really was possible it ran very toasty and eventually failed
    had to fix many units under warranty punishment was had.

    How about measuring the same signal when it’s not connected to the amplifier board. You could have a component that breaks down at a specific power level (12 o”clock) and loads the input signal down.

    Is it my imagination or was the signal on the oscilloscope really kind of triangular rather than sinusoidal?

      It does look very bad. must be upstream

    That's a pretty ugly sine wave at that jumper. I would remove it and inject rf there to see what power reaches the dummy load.

    My suspicion is the Auto Power Control has got the drive cut back cuz it thinks the VSWR is bad. Did I win? Am I the proud recipient of the ImsaiGuy IC-756 giveaway?

      @iowahank Well darn it! I always screw everything up. No free 756 for me!
